How do I create an ordered list of pairs of the following structure: {{x1,y1}, {x2,y2}, {x3,y3}, ...} ? I want x1, x2, and x3 to be increasing in constant-interval steps (e.g. 1,2,3) and similarly for the y's (e.g. 5,10,15). E.g. {{1,5}, {1,10}, {1,15}, {2, 5}, {2,10}, ...} etc. I cannot figure out how to do this with Table or Array. Is there another function that will do this? Table does not create the correct nesting or structure. Thanks! -Tony Hi, Tony, This: Table[{i,5*i},{i,1,5,1}] {{1,5},{2,10},{3,15},{4,20},{5,25}} is probably what you need. Otherwise you should explain what are you after in a more clear way. I strongly recommend that you should have a look into the documentation. This pays off astonishingly quickly. Go to Menu/Help/Table or Menu/Help/ContourPlot for your other question which I will not answer separately, and you will find there the answers to the questions you ask us. One more thing: when using Mathematica stop thinking the Pithon-way, think Mathematica-way. They are different. But first start consulting the documentation. Have fun.
